Briquet and binder for the same



UNITED STATES PATENT omce.

LUCIUS A. KINGKINNEY, OF GENTRALIA, WASHINGTON, ASSIGNOR T0 WILLIAM A.

GARLISLE, OF ONALASKA, WASHINGTON.

BRIQUET AND No Drawing.

T 0 all whom it may concern Be it known that I, LUOIUS A. KINGKIN- NEY, a citizen of the United States, residing at 216 N. Washington Ave, Centralia, in the county of Lewis and State of Washington, have invented certain new and useful Improvements in Briquets and Binders for the Same, of which the following is a specification.

This invention relates to binders for briquets and more particularly to a binder for briquets made of saw dust, wood fiber and the like.

The object of the invention is to provide a binder of the character indicated formed of materials readily available in'large quan tities and at small cost and capable of producing a briquet having great density and one that will be impervious to moisture, homogeneous throughout, capable of shipment and rough handling without breakage and will burn for an exceedingly long time.

Further objects and advantages of the invention will be hereinafter set forth.

It is a well known fact that millions of tons of saw dust go to waste, in the United States, every year. In order to utilize this otherwise waste product, I employ a binder made principally of waste products from other industries and from natural vegetable matter found in great profusion and readily available and by means of this binder produce briquets of saw dust and the like, having the desirable characteristics above set forth.

The aforesaid binder consists of the following ingredients, the amounts stated being such as I would use to form two tons of 'saw dust into briquets:

8 gallons of sulfite liquor, (waste liquor from paper mills).

20 pounds of gilsonite, (a well known asphalt like liquid).

4 gallons of a jelly derived from kelp or laminaria by macerating the natural weed and subjecting it to the action of sodium carbonate and water, preferably cold water, for

twenty-four hours.

The jell derived from the kelp is characterized y having a viscosity exceeding Specification of Letters Patent.

BINDER FOR THE SAME.

Patented Nov. 16, 1920.

Application filed May 12, 1920. Serial No. $80,888.

that of any known substance with which I am familiar. Its viscosity far-exceeds that of um arabic or well boiled wheat starch.

Iii forming briquets with this binder the saw dust, or other wood pulp or wood fiber, is subjected to heat until it is not only dry but is charred. It is then mixed with the binder while the latter is maintained in a heated oondition and, preferably, while the saw dust is still in its heated condition. When the whole has been reduced, by mixing, to an entirely homogeneous mass, it is compressed into the form of briquets in any suitable type of press, under great pressure.

These briquets dry rapidly, become exceedingly hard, will not break under handling in shipment, are impervious to moisture, may be stored in exposed places, without deterioration, for long periods, will ignite readily, will make a very hot fire and will burn for an exceedingly long time, practically without smoke.

It is to be understood that the invention is not limited to the precise proportions set forth nor to the exact combination of inredients recited but that it includes within its purview whatever chan es fairly come within either the terms or t e spirit of the appended claims.

Having described my invention, what I claim is- Y 1. ,A binder for briquets consisting of the following ingredients used in substantially the proportions stated, to two tons of wood fiber, sulfite liquor 8 gallons, gilsonite 20 pounds, a jelly derived-from kelp, 4 gallons.

2. The herein described process of forming briquets of saw dust, which consists of subjecting the saw dust to the action of heat to char the: same, and then mixing said charred saw dust, while still in its original heated condition, with a preheated binder consisting of, substantially, to two tons of saw dust; waste sulfite li nor 8 gallons, gilsonite 20 ounds and a elly derived from kelp 4 gallons, and then compressing the mixture into bri nets.

In testimony w ereof I hereunto afiix my signature.

LUCIUS A. KINGKINNEY.
